What is the BSB Number?

A Bank State Branch (BSB) number is the name used in Australia for a
bank code, which is a branch identifier.
BSB is used as an identifier consisting of a six digit numerical code
that identifies an individual branch of an Australian financial
institution.
The BSB is normally used in association with the bank account number.
For international transfers a SWIFT identifier is used in addition to
the BSB identifier and a bank account number.
